Globally, buildings are responsible for one-third of greenhouse gas emissions. Why are buildings such large contributors to greenhouse gas emissions? One, buildings typically rely on conventional energy sources for their power. And two, most buildings don’t use energy efficiently.

Because buildings are such a big part of the problem, they're an equally big part of the solution. To create greener buildings, we need to improve energy and water efficiency, reduce waste and pollution, transition to renewable energy sources, and use sustainable buildings materials. These strategies can reduce energy consumption in buildings by 30-80 per cent.
